Specification of Letters Patent.

Patented Oct. 31, 1905.

To all whom it nuty concern:

Be it known that we, JOHN WRIGHT SEAVER and ALFRED ERNST, residents ofCleveland, in

the county of Cuyahoga and State of Ohio, have invented certain new anduseful Improvements in Ramming-Machines; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

Our invention relates to an improved ramming-machine more particularlyadapted for compressing coal for by-product coke-ovens, the object ofthe invention being to provide a car or carriage carrying its own motor,which latter also automatically operates rammers at both ends of the caror carriage as well as propels the car back and forth over the coalbeing compressed, and provide handlevers whereby the entire operation ofthe apparatus is always under the complete control of the operator.

With these and other objects in view the invention consists in certainnovel features of construction and combinations and arrangements ofparts, as will be more fully hereinafter described, and pointed out inthe claims.

In the accompanying drawings, Figure 1 is a top plan view. Fig. 2 is aview in side elevation. Fig. 3 is a fragmentary end view, and Figs. 1and 5 are enlarged views in section, illustrating the plunger-bar clutchmechanism.

1 represents beams or framework on which rails 2 are located, and onwhich rails the wheels 3 of a car or carriage 4 are mounted to run. Ateach end of the carriage is a vertical frame or head 5, strengthened bybracebars 6 and having angle-iron bars 7 secured in opposite sides ofits open center and forming ways for guides 8, secured to thevertically-movable plunger-bars 9. The bars 9 carry plungers 10 at theirlower ends and are operated by our improved mechanism hereinafterdescribed.

On the car or carriage 1 an electric motor 11 is located,vand its shaft12 has a balancewheel 13 thereon. A pinion 14: on shaft 12 transmitsmotion to a larger gear 14 on a shaft 15, and a smaller gear 16 on theshaft meshes with a large gear 17 on a shaft 18, parallel with shaft 15and located near the center of the carriage or car. On the ends of theshaft 18 sleeves 19 are mounted and locked to turn with the shaft byclutches 20, operated by hand-levers 21 and 4:2, respectively, whichlatter extend to one side of the carriage and in convenient reach of theoperator. On the ends of these sleeves 19, which project outside of thecarriage, crank-arms 23 are secured and are connected by rods or links24; with crank-arms 25 on shafts 26, near the ends of the carriage, andas the crankarms 25 are considerably longer than crankarms 23 theturning of the latter simply oscillates the shafts 26. At the center ofshafts 26 crank-arms 27 are secured and are connected by rods or links28 with clutch-operating arms 29.

Sleeves 30 are mounted loosely on the plunger-bars 9 and are providedwith webs 31, which carry pins 32, and on these pins the arms 29 arepivoted. The arms 29 have sleeves or hubs 33, located on the pins 32,and said hubs or sleeves are cut away or recessed, forming shoulders 34in the path of grip pins or pieces 35, loosely mounted in openings inthe sleeves 30, and when the arms 29 are elevated the shoulders 3 1engage the grip-pieces 35 and force them into tight engagement with theplunger-bars and securely lock them to the sleeves 30, so that when thelatter are elevated by the crank-shafts 26 and arms 29 the plungers arelikewise elevated.

Laterally-projecting pins 36 are provided at the upper ends of webs 31,and bell-crank trip-levers 37 are fulcrumed on the pins 36, one memberof each lever connected by short links 38 with the pivotal connectionbetween the links 28 and arms 29 of its respective mechanism, and theother members of the trip-levers are slotted to move on the plungerbarsand project across the upper ends of the sleeves 30.

Suitably spaced apart and in the path of tripping-levers 37 stops 39 and40, respectively, are located, the former or lower stop serving as agripping-stop and the latter or upper stop constituting areleasing-stop, as will now be explained.

Assuming the parts to be in the position plunger-bar 9, locking thesleeve and bar together. Acontinued upward movement of the link 28elevates sleeve 30 and bar 9 until the trip iing-lever 37 engages thereleasingstop 40, when the contacting end of the tripping-lever will beforced downward, as shown in Fig. 5, and through the medium of the shortlink 38 will force arm 29 downward and release pressure on thegripping-piece 35, and the plunger-bar and plunger of their own weightwill fall to compress the coal. The reverse movement'of shaft 26 willforce the sleeve 30 downward until the tripping-lever 37 engagesgripping-stop 39, whichengagement compels upward movement of the end ofthe lever 37 in contact therewith. This movement of lever 37 through themedium of link 38 causes the initial upward movevment of arm 29, causingthe grip-piece to bind against the plunger-bar 9, when the operationabove described is repeated.

The parts shown are so arranged that the plungers at the ends of the caror carriage will be operated alternately; but it is to be understoodthat they may be operated simultaneouslythat is to say, while theconstruction shown will raise one plunger while the other falls theplungers might be respectively raised and lowered simultaneously.

On shaft 18 an eccentric 47 is loosely mounted and is locked to theshaft by a clutch 41, controlled by a hand-lever 22, and the band orstrap around this eccentric 47 is connected with an arm 43, secured on ashaft 44. A shaft is mounted in the carriage parallel with shaft 44, andsaid shafts 44 and 45 have intermeshing gear-segments 46, which compelthem to be simultaneously oscillated when arm 43is oscillated by theeccentric 47. Each of these shafts 44 and 45 has a depending arm 47, tothe lower end of which dogs 48 are pivotally secured, andcounterbalanced levers 49 are provided to hold the dogs in or out ofoperative position.

A notched rack 50 is provided on the framework, .and the dogs 48 projectin opposite directions, so as to propel the carriage in both directions,according to which dog is in op eration. I/Vith the parts shown in Fig.2 the left-handdog 48 at each movement of the shaft 44 engages in anotch of the rack and propels the carriage forward a distance of onenotch, which is of the same or less space than the width of the plunger.The other dog is held out of operation byits counterbalanced lever untilthe carriage reaches its extreme movement in one direction, when thecounterweighted levers 49 engage stops 51 and are thrown to theiropposite positions, thus throwing out the dog which had been inoperation and throwing in the other dog and reversing the direction ofmovement of the carriage.

In the upper portions of the plunger frames or heads cams 52 are securedupon cross-shafts 53 and are adapted to engage the plungerbars 9 andhold the plungers out of operation. These cams 52 are operated by levers54, connected with levers 55 at the center of the carriage by rods 56,and weighted arms 57 are secured on the shafts 53 to normally hold thecams out of engagement with the plungerbars.

It will be seen that with our improvements all of the controlling-leversare located adjacent to each other and enable the operator at oneposition to control the entire operation of the apparatus.

A great many slight changes might be made in the general form andarrangement of the parts described without departing from our invention,and hence we do not restrict ourselves to the precise details set forth,but consider ourselves at liberty to make such slight changes andalterations as fairly fall within the spirit and scope of our invention.
